Hi:

I'm designing a year's worth of English lessons for some Japanese kids, and I'm using Metapost and ConTeXt to generate flashcards for vocabulary training. I have a few questions:
(1) I want to keep my Metapost figures defined in a ConTeXt environment file so that I can recall them as I need in future lessons. Is there anything wrong with this approach?

sounds ok to me


(2) How do I make a Metapost figure defined in a ConTeXt file reusable? Do I need to wrap the definition of the figure in a macro so that the figure is recreated everytime I need it?

see patricks answer; in addition to that: external figures are reused by default


\startreusableMPgraphic{abc}

\stopreusableMPgraphic

\placefigure{]{\reuseMPgraphic{abc}}

will also be reused

(3) With \useMPgraphic, is there any mechanism to scale the image as with \useexternalfigure?

see patricks answer
